“…In other words, interocular asymmetries are greater in PACG in both the superior and inferior fields. The results of comparing the mean asymmetry of nasal fields were not significant and may indicate a more universal vulnerability of these nerve fibre layers during early phases in each disease, 3,8,9 or a lack of sensitivity of AGIS scoring techniques to detect subtle differences in nasal field loss.…”

Aim To compare the interocular asymmetry in visual field loss of patients with primary open-angle (POAG) and primary angle-closure glaucoma (PACG). Methods Subjects entering a prospective, randomised, controlled trial of intraoperative 5-fluorouracil in glaucoma surgery in Singapore were included. Preoperative visual field testing was performed using automated white-on-white perimetry (24-2 test pattern, threshold program, Mk II, Model 750, ZeissHumphrey, San Leandro, CA, USA). A minimum of two tests were required with mean deviation within 2 dB on two tests, fixation losses o20%, false positives o33%, and false negatives o33%. The second field was scored using AGIS II criteria and the 'mean asymmetry score' defined as the mean difference between eyes for both AGIS scores and global indices. Results In 230 subjects assessed (128 POAG, 102 PACG), mean interocular asymmetry of visual field loss was greater for the PACG group. The mean AGIS asymmetry scores for total (PACG ¼ 9.2176.87 vs POAG ¼ 6.4875.58, P ¼ 0.001), superior (PACG ¼ 4.3173.39 vs POAG ¼ 3.3573.13, P ¼ 0.035), and inferior (PACG ¼ 4.4373.31 vs POAG ¼ 2.6472.77, Po0.0001) areas and mean deviation (MD) asymmetry scores (PACG ¼ 6.89713.22 vs POAG ¼ 1.66716.97, P ¼ 0.012) were all significantly different. Interocular correlation of visual field loss for POAG was significant; total AGIS, r ¼ 0.27 (P ¼ 0.003), superior field AGIS, r ¼ 0.24 (P ¼ 0.008), inferior field AGIS, r ¼ 0.34 (P ¼ 0.0001), and MD, r ¼ 0.27 (P ¼ 0.003). In PACG, there was no significant correlation between eyes; total AGIS, r ¼ À0.02 (P ¼ 0.85), superior field AGIS, r ¼ À0.02 (P ¼ 0.82), inferior field AGIS, r ¼ À0.17 (P ¼ 0.87), and MD, r ¼ 0.015 (P ¼ 0.89). Conclusion There was a greater asymmetry of visual field loss between eyes, as measured by AGIS scores and MD, in PACG than that in POAG.

“…2 The resulting prolonged elevated intraocular pressure (IOP) in turn leads to irreversible optic nerve damage and visual impairment. [3][4][5] The definitive treatment is cataract extraction after initial control of intraocular pressure with medical or laser therapy (laser iridoplasty, LI and or laser iridotomy, ALPI) to prevent the risks of operating on an eye with corneal oedema and high IOP.…”

“…Outros autores observaram que a distribuição dos defeitos precoces no campo visual em 214 olhos de pacientes com GPAA inicial revelou uma combinação de escotoma paracentral com defeito periférico em 75,2% (17) . Nosso estudo difere de outros que demonstraram que os defeitos perimétricos mais freqüente-mente detectados por meio da perimetria manual foram, em ordem decrescente: escotoma arqueado, degrau nasal, escotoma paracentral, escotoma Seidel, e defeito temporal em cunha, sendo a região superior mais acometida que a inferior (6) . A diminuição generalizada de sensibilidade é um defeito pouco freqüente no glaucoma e pode ser considerado um defeito precoce, porém é inespecífico, pois pode estar presente em outras neuropatias ópticas (18) .…”

“…(Swedish Interactive Threshold Algorithm) zada são observadas quando cerca de 40% das fibras ganglionares já foram lesadas (5) . O defeito inicial mais freqüente é o degrau nasal, que pode ou não estar acompanhado de escotoma paracentral (6)(7) . Aquele evolui lentamente em extensão e profundidade, ou com a formação de um novo escotoma.…”
